摘要
针对火箭弹增程问题,提出了以攻角为优化变量的实时优化方法。基于制导弹药的纵向平面模型,建立了制导火箭弹弹道模型,采用改进单纯形优化算法在SIMULINK中实现了函数子模块优化,对某型制导火箭弹弹道进行实时优化仿真。结果表明:采用改进单纯形的攻角实时优化,可以在保证火箭弹飞行稳定性的前提下有效增加火箭弹射程,且增程率达到74.3%,对火箭弹增程研究具有一定指导意义。
Aiming at the problem of the range extension of rockets,this paper proposes a real-time optimization method with the angle of attack as the optimization variable.Based on the longitudinal plane model of guided munitions,the article establishes the trajectory model of extended-range rocket.The improved simplex optimization algorithm is used to optimize the function sub-module in SIMULINK,and the trajectory of a guided rocket is optimized in real time.The results show that the real-time optimization of the angle of attack using the improved simplex can effectively increase the rocket’s range,under the premise of ensuring the stability of the rocket’s flight,and the range increase rate reaches 74.3%,which has certain guiding significance for the research of rocket range extension.
